摘要： The invention relates to a valve, in particular a suction valve, in a high-pressure pump of a fuel injection system, having a valve element (14) which can be moved between an open position and a closed position and which is connected to a magnet armature (10) via an armature pin (8). An actuation force can be transmitted to the valve element (14) by the armature pin (8). The invention is characterized in that the armature pin (8) is partly introduced into a depression (24) of the magnet armature (10), and the armature pin (8) and the magnet armature (10) are connected together in a contact region (48) in a force-fitting manner by means of an interference fit (20). The armature pin (8) has a changing outer diameter (47), in particular a continuously changing outer diameter, along the contact region (48).
